The Flat Tire Brand Tube Pad is made from repurposed industrial inner tubes and crafted for comfort and toughness. Tube Pads are industrial strength, yet soft, which ensures comfortable knee protection. This semi-circular shape offers a kneeling area that is larger and more spread out than traditional kneeling pads. A larger area combined with superior padding means technicians can be on their knees longer, and more comfortably, to get the job done, according to the company. Tube Pads are extremely durable, soft and comfortable, waterproof, made in the U.S.A. and come with a craftsmanship guarantee.
